OIL-BURNING RANGE.

To all whom it may concern:

Be it known that I, GEORGE T. Joonnns, a citizen of the United States, and a resident of the borough of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Oil Burning Ranges, of which the following is a specification suflicient to enable others skilled in the art to which this inven tion appertains to utilize the same.

My improvements relate to heating and cooking ranges generally, in which the fuel used is atomized oil injected into a fire box in a manner Well known in the prior state of the art,my invention being the result of experimental investigation undertaken for the purpose of attaining perfect fuel combustion and the effective utilization of the full caloricvalue thereof; and consisting in the specific construction, combination, and arrangement of parts and appurtenances described and claimed, whereby original and important results are attained, all as hereinafter fully set forth.

In the accompanying drawings I eXem- V plify a practical embodiment of the essen tial features of my invention, in a duplex type of range, although I do not limit myself to the identical form and construction shown in this connection in so far as minor details are concerned, 'sincefmodifications, and equivalent mechanical expedients, may be resorted to with like effect, and without departing from the spirit and intent of my invention in this respect.

With this understanding,

Fig. 12, is a horizontal section taken upon plane of line 12 -12, Fig. 7.- Fig. 13, is a diagram illustratingtheopen oven door support in conjunction with Figs. 8 and 9. v I herein show and describe my new and improved oil'burning range as adapted par ticularly to the-requlrements of use infshlp galleys, although the main features in the construction and arrangements of parts are for hotels, restaurants, &c.

equally adapted for use for cooking ranges The fire brick b, or other refractory matecasing serving as an extraneous heating and cooking surface,'-a guard rail R,eXtend-ing around said top plate 0', said guardrail R, belng provided with transverse bars 1',

r, and the whole rail functioning to retain' cooking utensils, etc;, positionedupon the top plate. 0, an essential precaution 1n the case of marine ranges. h, is a-hand rail such as usuallyprovided on the upperfront portion of such ship ranges.

In the duplex and bi-laterally symmetrr cal construction and arrangements of parts shown herewith the combustion chamberyt,

' Figs. 5 and 7, off'the drawings. The bottomfofthe combustion, chamber a, consists of a block b, of fire brick, in which is formed a forwardly inclined gutter b", the floor of which leads-to a drain piped, through which surplus unconsumed oil is drawn oft, thereby obviatingall danger of explosion and preventing waste of fuel;

' perfect gaseousness preparatory to the 6X- of the ovens opposite to the combustion chamber a, and its direct vertical flue a, as shown more particularly in Fig. 7 of the drawings; and both'these sideflues a a and said direct flue a, lead to and communicate with horizontal flue spaces a a, above the ovens V, V, and beneath the top plate 0', which top flue spaces a, a communicate indirectly with the stack S, through which the products of combustion are finally discharged. These upper flue spaces a*, a are shown connectively and collectively more particularly in Fig. 8, of the drawings, in which 6 Z2 represent fire brick baflles which insure an equitable distribution of the products of combustion over the topsof the ovens V, V, as said products of combustion pass to the stack S.

The fuel oil is injected in the form of spray into the combustion chamber a, through a nozzle n, preferably of the type described in my Letters Patent No. 1,450,000.

issued March 27th, 1923, or by any equivalent means. r

'6 is'an air inlet passage in the front of the range .positioned above the oil injecting means, and provided with one or more'doors 0 0 or equivalent means for regulating the admission of air to the combustion chamber a, to prescribe the quantity of oxygen essential to insure the incandescence and-reduction of the nascent oil spray in the said combustion chamber to treme of such products of combustion into the flues on their way to the discharge stack S. Ignition of the fuel within the combustion chamber may be effected through said air inlet 5 or through the top of the direct flue a, by the removal of the central cover 0 on the top plate 0 as will i be understood by reference more'particularly to Fig. 5, of the drawings.

Said; central cover 0 rests on a concentrio annular cover 0 in turn supported on a removable central plate 0 which 'is flanked by two other top platesc 0. The

' openings closed by the cover plates 0 and 0*, are provided for the accommodation of pots, pans, etc., to be subjected to the direct heat of the main fine a; andlthese 7 larger cover platesc 0 and a, give access to the top fines for cleansing purposes, or for the accommodation of cooking utensils of larger size, accordingf to circum stances and requirements of use. Obvious- 1y, theflankting ,top plates 0 0, may be formed, if desired, with circular openings for' pots, etc, closed normally by suitable covers as 'in the case of the central top cover plate a. V r

*E'QE, are compartments in the casing below the ovens V, V, closed normally'by doors e,- e, and whichspaces may be'utilized for-the purpose of the temporary storage of plates, dishes, or cooking utensils which it is desired to keep warm, said spaces E, E, performing a double function in that they not only act asv heating compartments as above stated, but also act as non-conducting areas to prevent loss of heat, and keep the floor cool.

The top, bottom and sides of the oven shells are made in one piece to facilitate replacement when desirable, in which case it is simply necessary to temporarily remove the upper brick work in order to remove an old shell and substitute a new one.

The doors V, V, of the ovens V, V, are pivotally supported at their lower edges by trunnions c, a, mounted in bearings in side brackets o, v, on the door frames c c as shown more particularly in Fig. 8; and they are held closed normally by slidable bolt bars a" which engage with hooks 41 on the upper part of said door frames c '0 as indicated in both Figs. 8 and 9, of the drawings, o representing lifters by means of which the doors may be latched or unlatched. In order to support the doors when open, I provide side bracket arms h, h, fulcrumed in'socket pieces 0 0 on the front plate c of the casing 0, the outer ends of said bracket arms h, it, being formed with lugs h, h, which fit in shouldered grooves 0*, 11*, in the side members of the doors V, V, as will be understood by reference more particularly to the aforesaid Figs. 8 and 9, of the drawings. Thus when a door is opened and lowered into horizontal position 'asindicated diagrammatically in Fig. 13, the bracket arms h, it, will act asbraces to support said door in such position.

It is to be understood that this special form of oven door V, and'articulative sup ports, forms no part of my present invention, the distinctivefeature of which is the novel construction and arrangement of the; range fiues, and accessories relating thereto, whereby the products of combustion are. caused to pass under, around, and over'the ovens, in a manner essentially direct to the' discharge stack, but never in a reverse or downward direction as'in the prior state of the art.

By my method of insuring a continuous upward and forward passage of the prodnets of combustion as related to the discharge stack, and around and on all sides of the oven, I attaina relatively high degree of temperature in the oven with a minimum amount of fuel oil, practical and comparative testshaving demonstrated the fact that the use of a pint of oil in my improve'd structure of oil burning range will insure results equivalent to those attained byan' expenditure of two gallons of'oil in ranges of this class; as heretofore constructed. Fur thermore, I attain this economical desid eraturn with greater safety because leakage and seepage of oil is eliminated, with all danger of extraneous fire or explosion; and in this connection it may be mentioned also that explosion of oil within the combustion chamber is avoidedby the draining off of all drip or surplus oil that might otherwise collect in the bottom of said combustion chamber.

It is to be understood that while I herein illustrate the essential principles of my invention as embodied in a twin oven range,"

the same may be utilized for a single oven range with like results, distribution of heat to oven space is attained in either case, as well as to the heating surfaces constituting the top of the range.

Furthermore, it is to be understood that by the term fire-brick as herein used I mean to designate any refractory material known commercially as by that name, or any equivalent thereof, said body structure of refractory material being indispensible in a range of this character in which the intense heat generated by oil-spray combustion would otherwise result in a speedy deterioration and destruction of the range, considered in its unitary sense.

What I claim as my invention and desire to secure by Letters Patent is,

1. A substantially all fire brick range embodying afire-brick enclosing structure with an oven therein, a combustion chamber beneath the oven, a vertical flue. and lateral horizontal flues around the oven, the bottom of said combustion chamber comprising a fire brick block with forwardly-inclined gutter, the upper wall of the oven having horizontal flue spaces, and fire brick battles to insure distribution of the products of combustion over the top of the oven.

2. An oil burning range comprising a fire box and means for injecting fuel thereto,

in that an equitable a flue extending upwardly from the fire box, the back wall of said flue and box being formed with a gradual curve to the top of the structure and extending approximately half the distance from front to rear of the range.

3. An oil burning range with a fire box and a flue extending to the upper front part of the range, horizontal extension flues 'at each side of the upper end of said first flue, and baflles forming the back of said second flue and extending outwardly behind the first flue.

4. An oil burning range with a fire box and a flue extending to the upper front part of the range, horizontal extension flues at each side of the upper end, of said first flue,

baflles forming the back of said second flue,

and extending outwardly behind the first flue, and other baffles at right angles to the first-named baffles.

5. An oil burning range with a fire box and a flue extending to the upper front part of the range, horizontal extension flues at each side of the upper end of-said first flue,

baffies forming the back of said second flue and extending outwardly behind the first flue, and twin ovens in proximity to the said flues. V

6. An oil burning range with afire box and a flue extending to the upper front part of the range, horizontal extension flues at each side of the upper end of said first flue, baffles forming the back of said second flue and extending outwardly behind the first flue, other baflies at substantially right angles to the first-named baflies, and twin ovens in proximity to the said flues.
